Two disc jockeys charge different rates. the music man charges $45 per hour and road tunes charges $35 per hour . write equations to represent the total cost y or hiring either disc jockey for any number of hours n

d. vertex

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2
